1. System description
1.1 General
The Hydro
DOS
®
system is designed as a cabinet
system and is used for the production of chlorine
dioxide.
A chlorine dioxide solution is automatically
produced from the chemicals hydrochloric acid
(9%) and sodium chlorite (7.5%).
Both reactants are mixed in a reactor chamber so
that a solution with a maximum concentration of
20 g/l is available for dosing. The chlorine dioxide
concentration is then substantially diluted in the
by-pass-path.
Coming from the consumer feed/cold water
storage tank, a part flow volume is fed to the
chlorine dioxide system, dosing agent added and
fed again in the consumer feed or water storage
tank.
Corresponding
measuring
equipment
(for
chlorine dioxide and flow volume) is provided to
control dosing.
Due to the concept and control of the plant, all
operation states guarantee a secure operation.
Application:
- Removal of odorous and flavouring
substances.
- Inhibition of algae growth in open storage
systems.
- Slime combat in cooling systems and open
circuits.
- Disinfection of filter and softener systems.
- Disinfection of water containing ammonia
traces possible.
- Degeneration of biofilms in pipe systems.
- Legionella combat and stabilizing of
contaminated systems.
- Disinfection within a broad pH-value range.
